吸附型生物絮凝剂ZL5-2的制备及在水处理上的应用

Preparation of adsorption-type bioflocculant ZL5-2 and its application on water treatment

研究了吸附型生物絮凝剂ZL5-2对印染污水、炼油污水、生物工程发酵液的絮凝作用,并同聚合铝絮凝剂对污水和发酵液的絮凝作用进行了比较。经ZL5-2絮凝作用,炼油污水絮凝率为74.7%,COD去除率为32.4%,BOD去除率为55.4%;印染污水絮凝率为65.8%,COD去除率为49.5%,BOD去除率为62.3%;青霉发酵液和灰色链霉菌发酵液絮凝率最高可分别达到68.4%和69.0%。

Bioflocculation of the wastewater let off from printworks, refinery and microbe from fermentation by the novel adsorption-type bioflocculant ZL5-2 has been studied and compared with the flocculability that polyaluminum flocculant flocculated the wastewater and the microbe. The flocculability of the wastewater from printworks and refinery are 74.7% and 65.8% respectively, and COD reduced 32.4% and 49.5% respectively, and BOD reduced 55.4% and 62.3% respectively. The flocculability of the penicillium ferment and the actinomycetes ferment are 68.4% and 69.0% respectively.
